    PR14179: Merge staprun/configure into the root
    
    We were duplicating some logic by having separate configure files.  The
    especially doesn't make sense when you consider that staprun et al. even
    build some ../ sources files as well.  Now the configuration is shared
    all at once.  (Makefiles are kept separate though, at least for now.)
    
    A few changes to highlight:
    
    - The root configure now uses AC_SYS_LARGEFILE, which makes a more
      informed decision about _FILE_OFFSET_BITS=64.  Thus, rather than being
      forced in stap_CFLAGS, this will now be set in config.h, and only on
      targets that aren't natively 64-bit.
    
    - staprun can now link to the --with-elfutils version of libelf.
    
    - The run-staprun helper script now also passes LD_LIBRARY_PATH through
      sudo, to help the --with-elfutils case.  We generally don't support
      run-stap and run-staprun, except for power users/developers, so those
      people should make sure their environment is clean.

    PR14179: Move staprun et al. out of runtime/
    
    We will reserve runtime/ for those files that are built into the
    stap-generated module, whereas staprun/ contains source for the various
    prebuilt executables for running those modules.
